Tóm tắt giúp mình bài này với ạ In a room at Stanford University, scientists have a problem with their robot. It can walk up and down walls made of glass and plastic, but it cant walk upside down. So today, they have a gecko in the room. The gecko is an amazing animal. Like the robot, its very good at moving up and down trees, but the gecko can also walk upside down. In particular, the scientists are interested in the geckos feet. They want to learn from its feet and use the same design on their robot. Animals and plants can teach humans a lot about design and engineering. As a result, many engineers, scientists, and designers spend time studying the natural world. When they have a question, nature often has the answer. This science is called biomimetics. Bio- means living things, and mimetics means copying. In other words, these scientistsor biomimeticistsdepend on animals and plants to help them solve design problems. Two types of sea animals helped engineers in Canada and Germany. When engineers in Canada were working on improving wind turbines, they studied a whales flippersbecause whales move so easily through water. And when the car company Mercedes-Benz wanted to think of a new design for a car, it looked at a boxfish. The result was a car that was similar to the shape of a boxfish and that used less fuel than other cars. The world of plants helped with the invention of Velcro and a new type of paint. In 1948, the Swiss engineer George de Mestral was walking in the countryside when he pulled a plants bur² from his pants. He noticed how the bur stuck really well to his clothes, and this gave him the idea for Velcro. And in 1982, Wilhelm Barthlottan inventor who was studying the leaves of a lotus plantnoticed that water always ran off the leaf. Barthlott copied the lotus leafs design and produced a type of paint that stays cleaner than regular paint because water and dirt run off it. Biomimetics has helped to solve modern human problems, and there are many more possibilities. It might take a long time to discover all of them, because, after all, it has taken nature millions of years to design its animals and plants.
